Answer:
t = -1.042, when s = 4 m/s
Step-by-step explanation:
The finishing time of the runner is given as the function of tail-wind speed.
t = 0.0119 s² - 0.308 s - 0.0003
We have to find t, when s= 4 m/s
Substitute s = 4, in the above equation
t = 0.0119 (4²) - 0.308 (4) -0.0003 = 0.1904 - 1.232 - 0.003 = -1.0419
Rounding it to the nearest hundredth, we have,
t = -1.042
∴ t = -1.042, when s = 4 m/s.
Answer:
b. A small P-value.
Step-by-step explanation:
The p-value is used to study the validity of a test. Basically, it tests if the result found is due to a small sample, for example, or that if the result is really statistically significant.
A small pvalue is a strong evidence against the null hypotheses, which indicates statistically significant results.
So the correct answer is:
b. A small P-value.
